attributes disk

  • Article

Displays, sets, or clears the attributes of a disk. When this command is used to display the current attributes of a disk, the startup disk attribute denotes the disk used to start the computer. For a dynamic mirror, it displays the disk that contains the boot plex of the boot volume.

Important

A disk must be selected for the attributes disk command to succeed. Use the select disk command to select a disk and shift the focus to it.

Syntax

attributes disk [{set | clear}] [readonly] [noerr]

Parameters

Parameter Description
set Sets the specified attribute of the disk with focus.
clear Clears the specified attribute of the disk with focus.
readonly Specifies that the disk is read-only.
noerr For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code.
